DESCRIPTION

The 66325 high voltage isolator consists of an 850 nm LED optically coupled to a high gain inverting photon detector. The

isolator provides high CTR and low leakage currents over the specified temperature range of -40ºC to +100ºC.The isolator is

built with hermetic components internally optically coupled and encased in a high temperature outer PPS plastic housing.
